To allwkom itmtty concern:

Be it known that I, ERNEST H. FALLEN- STEIN, a citizen of the UnitedStates, residing at Mankato, in the county of Blue Earth and State ofMinnesota, have invented a new and useful Cableway Excavating- Bucket,of which the following is a speci fication.

This invention relates to excavating buckets, and more particularly toan excavating bucket designed to move over a cable,- way, it being theprimary object of the invention to provide means for locking-the bucketagainst pivotal movement with respect to its bail to eliminate anypossibility of the bucket dumping while the same is carrying its load.

A further object of the invention is to provide means controlled by thedumping cable to unlock the bucket and permit the same to readily dumpits contents.

A still further object of the invention is to provide a lock which willbe held in operation by the weight of the contents of the bucket,associated therewith.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings Figure 1 illustrates a side elevational Viewof a bucket constructed in accordance with the present invention andshowing the same in its locked position.

Fig. 2 illustrates a side elevational view of the bucket showing thesame in an unlocked position.

Fig. 3 illustrates a perspective view of the bucket in its lockedposition.

Fig. 4 illustrates a rear elevational view of the bucket and Fig. 5illustrates a view showing the bucket on its supporting cables.

Referring to the drawings in detail, the bucket comprises a supportembodying opposed legs 5 and 6, which are formed at their upper endswith inwardly extending portions to provide a bail 7 the extreme upperends being connected as by means of type and includes opposed bearingmembers 13, which bearing members receive the pivot pins 14 for securingthe pins to the support.

As shown, these bearing members 13 are disposed in spaced relation withthe opposed legs of the supporting bail to provide a. clearance for theends of the locking bail 15, which forms an important feature of thepresent invention, the locking bail being however pivotally mounted onthe pins let.

The bucket indicated at 16 is supported between the opposed legs of theauxiliary bail 9, to move therebetween, the pivot point p of the bucket16 being adjacent to the forward extremity of the bucket to permit thebucket to tilt rearwardly under the weight of its load.

Extending laterally from the bucket walls are the bolts 17 that aredisposed adjacent to the upper rear corners of the buckets, which boltsprovide bearings for the rollers 18, which are designed to move in thecut out portions 19 of the locking hail, the cut out portions beingprovided with right angled extremities providing seats for the rollers18, when the bail 15 is in its locking position.

An operating cable 20 has connection with the locking bail 15 as throughthe links 21, which operating cable passes over the roller 21' mountedbetween the side walls of the carriage 22 from where the same passesover the pulley 21 which is supported by the cable standard 23.

The bridle cable 24. connects with the bucket 16 through the pivotedarms 25 which are mounted on the supporting bolts 26 that connect thebucket 16 to its support, and this bridle cable 24 is wound on asuitable drum not shown, whereby the bucket may be forced into a sand orgravel pile, to cause the bucket to pick up a quantity thereof.

From the foregoing it will be seen that as the forward portion of thebucket 16'is drawn toward the material to be scooped thereby, the weightof the material passing into the bucket, tilts the same rearwardly,causing the rollers to move in the slotted trackway or cut out portion19 until the same seat themselves in the right angled portions of thetrac-kways with the result that the bucket 16 is locked in its carryingposition.

' WVhen the bucket has been moved to a 10 cation where the same maybedumped, the

operating cable 20 is moved to release the locking bail 15, whereuponthe load or contents of the bucket may be deposited. It might be furtherstated however that a plurality of teeth 27 are carried at the forwardextremity of the bucket, to cause the bucket to readily penetrate a sandor gravel facilitate the loading of the bucket.

While I have shown the bucket as supported on suitable cables, it is tobe under-- stood that I have not gone into thedetails of thisconstruction, since the essence of the'invention resides in the bucketlocking feature.

Having thus described the invention, what I claim as new is 1. Anexcavatlng bucket lncluding a suppile to I port, a bucket sectionpivotally mounted within the support, rollers carried by the bucketsection, a locking bail associated with I the bucket section, saidlocking bail having slotted trackways to accommodate the rollers, saidtrackW-ays having right angle porfor operating the locking bail torelease the bucket.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses. V
